Color-to-alpha only applies to the selection, so you can restrict its 
effects by doing a selection first. For instance to remove a background, 
use the wand to get a rough selection of the background, grow the 
selection by  a couple of pixels so that it includes the edges of the 
foreground, and perform color-to-alpha.
